core, core/state, trie: Hardfork EIP155, EIP161, EIP170

2016-11-15T11:40:36+00:00

This commit implements EIP158 part 1, 2, 3 & 4 1. If an account is empty it's no longer written to the trie. An empty account is defined as (balance=0, nonce=0, storage=0, code=0). 2. Delete an empty account if it's touched 3. An empty account is redefined as either non-existent or empty. 4. Zero value calls and zero value suicides no longer consume the 25k reation costs. params: moved core/config to params Signed-off-by: Jeffrey Wilcke

[release/1.4.18] core: fixed import reporter

[release/1.4.18] core: print import stats more often

2016-10-15T09:02:43+00:00

If geth is busy importing 2048 heavy blocks it can take a while before it prints anything. This change ensures that a message gets printed every 8s. (cherry picked from commit e66b158f0bf85edf39edc978241226cb8f7df45b)

[release/1.4.18] core, core/vm: added gas price variance table

2016-10-14T16:46:38+00:00

This implements 1b & 1c of EIP150 by adding a new GasTable which must be returned from the RuleSet config method. This table is used to determine the gas prices for the current epoch. Please note that when the CreateBySuicide gas price is set it is assumed that we're in the new epoch phase. In addition this PR will serve as temporary basis while refactorisation in being done in the EVM64 PR, which will substentially overhaul the gas price code.

[release/1.4.18] trie, core/state: improve memory usage and performance (#3135)

2016-10-14T16:46:36+00:00

* trie: store nodes as pointers This avoids memory copies when unwrapping node interface values. name old time/op new time/op delta Get 388ns ± 8% 215ns ± 2% -44.56% (p=0.000 n=15+15) GetDB 363ns ± 3% 202ns ± 2% -44.21% (p=0.000 n=15+15) UpdateBE 1.57µs ± 2% 1.29µs ± 3% -17.80% (p=0.000 n=13+15) UpdateLE 1.92µs ± 2% 1.61µs ± 2% -16.25% (p=0.000 n=14+14) HashBE 2.16µs ± 6% 2.18µs ± 6% ~ (p=0.436 n=15+15) HashLE 7.43µs ± 3% 7.21µs ± 3% -2.96% (p=0.000 n=15+13) * trie: close temporary databases in GetDB benchmark * trie: don't keep []byte from DB load around Nodes decoded from a DB load kept hashes and values as sub-slices of the DB value. This can be a problem because loading from leveldb often returns []byte with a cap that's larger than necessary, increasing memory usage. * trie: unload old cached nodes * trie, core/state: use cache unloading for account trie * trie: use explicit private flags (fixes Go 1.5 reflection issue). * trie: fixup cachegen overflow at request of nick * core/state: rename journal size constant (cherry picked from commit 40cdcf1183df235e4b32cfdbf6182a00a0e49f24)
